Phosphate is an end product from the breakdown of organic substances such as food remains, fish feces, etc. In high concentrations it can cause algae growth. Phosphate is also an important source of nutrition for aquarium plants. However, it is preferable to keep the PO4 value in the aquarium as low as possible. Values up to 0.5 mg/l are acceptable. Use this phosphate test regularly to gain insight into the processes in the aquarium.
NB! Phosphate tends to form highly soluble salts that settle on the bottom together with the sludge. So regularly remove the sludge from the bottom.
This test reliably and accurately measures the Phosphate value in freshwater, seawater aquariums and ponds

A high phosphate value in the aquarium does not necessarily have to be a problem. As mentioned, phosphate is an important nutrient for plants. In an aquascape with many plants and relatively few fish/waste products, little phosphate naturally enters the water. In such a situation it may even be useful to add phosphate.
If there is more phosphate present than the plants can absorb and there is therefore an incorrect balance in the aquatic environment, the phosphate value can be reduced in the following way:
- feed less
- change more water
- remove dirt from the bottom and from the filter
- keep fewer animals in the aquarium
- place more (fast-growing) plants in the aquarium
Gekocht om mijn aquarium water te testen. Levering inclusief een duidelijke handleiding. Wat misschien beter zou kunnen is een glazen buisje ipv een plastic variant. Bij Sera zit er standaard een glazen exemplaar bij.
